re: How often do you clean your family member’s grave?

My family had an uncle that was killed in World War II and buried in Europe. For a long time (pre-internet) we didn't know where, just that he died fighting in Germany at the very end of the war and they buried him somewhere with his brothers in arms. We later found out he was buried in a military cemetery in the Netherlands.

It turns out this town in the Netherlands where the US military cemetery is located assigns a resident of the town to take care of a specific grave and if you go over there to visit the grave of a family member you can meet this person who takes care of your grave. Some random Dutch woman cleaned my uncle's grave and put flowers on it for over 30 years. She never knew him obviously. Every grave has a personal caretaker and it is a great honor that they take very seriously. Those WWII cemeteries are hallowed ground to them. Pretty cool.
